[openib-general] RDMA Read performance

Hello,

I am using RDMA READ for an internal application and I am seeing 
problems with performance on OpenIB. I am not seeing the same 
performance problems on like hardware using Mellanox VAPI. Perhaps I am 
doing something silly. Attached is a patch to rdma_bw.c where I am 
seeing only ~192MB/sec which should be closer to 950MB/sec.

Any help or ideas are appreciated.

Thanks,

Galen
